Problems solved by technology

However, once it is applied in the automotive field, it cannot meet the minimum requirement of HONDA series car seats: 25MJ/m 2 Under the condition of light intensity, it can reach 3 grades of fading and 4 grades of discoloration
[0005] Although from the perspective of single color dyes, there are still some yellow dyes that can meet the standards of the automotive industry, but once they are used in combination with other compound dyes, problems such as poor application performance and low performance often oc

Example Embodiment

[0056] Example 1-28

[0057] After the three dye monomers and auxiliary agents are mixed according to the weight parts listed in Table 1, they are ground and dispersed with a sand mill, and then spray-dried to obtain the yellow disperse dye composition of the present invention.

[0058] Table 1 Composition of the yellow dye composition of the present invention

[0059]

[0060] According to the yellow composition provided by the present invention, the fiber can be colored in a high temperature and high pressure dyeing machine at a temperature of 130 to 135° C. by using an aqueous dispersion in a traditional dyeing method.

[0061] The above embodiments are tested using the attached color fastness test standard, and the color fastness is shown in Table 2.

Example Embodiment

[0075] Example 29

[0076] The yellow dye composition obtained in Example 11 was used in combination with the blue dye and the red dye to obtain a beige and light gray dye composition. The weight percentage composition and light fastness test results are listed in Table 7.

[0077] Among them, the red dye composition is a mixture of 30 parts by weight of Disperse Red 60, 12 parts by weight of Disperse Red 146 and 1 part by weight of Disperse Red 92, and the blue dye composition is 6 parts by weight of Disperse Blue 56, 12 parts by weight of Disperse Blue 60 and 16 parts by weight of a mixture of Disperse Blue 77. The preparation method is the same as that of the yellow dye composition of the present invention. Each dye monomer also uses disperse dyes of corresponding colors produced by the Changzhou Yabang factory.

Abstract

The invention discloses a yellow disperse dye composition with high light fastness. The yellow disperse dye composition comprises at least two yellow dyes shown in structural formulas (I), (II) and (III), wherein R is methyl, ethyl or propyl. The yellow disperse dye composition has stable light fastness under the condition of long-term irradiation, particularly when the dye ensures relatively light color in the final dyeing, the light fastness is superior to that when the color is relatively dark, and can meet the requirement of light fastness of the color of intermediate-grade auto inner ornamental cloth.

Description

technical field [0001] The invention relates to the field of disperse dyes, in particular to a yellow disperse dye composition with high light fastness and its application. Background technique [0002] In recent years, hydrophobic fiber materials, especially polyester fibers, have been widely used in automotive interior decoration, especially as a material for seat sheets. As the importance of automotive interior styling has increased, there has been a greater demand for richer colors. When used as a sheet for automotive interior decoration, color fading is prone to occur due to long-term high-temperature exposure, and it is difficult to maintain a good color for a long time. Therefore, the dyes used for dyeing automotive fabrics must meet the requirements of light fastness, especially the dyeing fastness to light at high temperature. [0003] Often, high temperature exposure causes yellow fading and discoloration, which becomes the cause of discoloration in mixed dyes wi...
